Quicksilver 430 Keel Pressure

Hi folks, hopefully someone might be able to help me out.

Bought a Quicksilver 430 with a Yam 25 outboard from eBay a few days ago to use on the river and take to the beach etc etc.

I think it's a good one but I'm not sure on a suitable pressure for the keel?

Have the tubes at .25 which I think is about right but the inflatable keel is lacking and I'm unsure how far to go with the pressure before I put too much in.

Any advice welcomed

Scott.

Hi Scott .. If its the quicksilver 4.3 HD with the wooden or ali flooring..the keel should be the same as the tubes .. ie 250 mb or 0.25 bar..thats quoted from the owners manual..cheers

Thanks for that, I had read .25 for the lot but just seems a bit under inflated. But that said if that's what it is then I'll stick with it.

Cheers Scott

If having a wooden floorlboard up front and inflating keel to 0.25 Bar/3.5 PSI with time and ridding constantly on choppy waters will end cracking floorboard where air valve pops out or abrading upper keel against floorboard. 0.20 bar/3.0 psi will be sufficient for excellent sib water performance.

My 430 hd has it written on it and from memory the keel requires more. I remember it being quite hard to pump. Plus you can't really trust the pressure guages as I am on my 3rd and its still rubbish.

Should be over at boat next couple of days so will let you know.

My 380 Ali floor SIB keel needs to be at .35 bar and the tubes at .25 bar

Saying this, I've recently noticed my pump only goes up to .30 bar so I've never fully inflated my keel.

I wonder if the .05 bar would make a difference? Anyone?

That's due being a low volume bladder like as opposed to a sib's tube which holds much more air volume and consequently much easier to inflate.

Keel works along nicely when sib's tubes have been inflated to its recommended working pressure for floor fabric to stretch out and achieve along with well inflated keel a perfect formed tent like shape under deck.

Try with min 3.0 psi once sib is floating for some minutes on water for pressure to stabilize, re inflate if needed, test to higher pressures to see if any difference at all on a flat glassy no wind water cond.

Happy Boating

Bugger, looked yesterday and think I remember!
Pretty sure it was .44 bar, 6.2 psi. Or 6. Something. I know its not easy to pump. Will look again in a few days

Just to confirm, looked yesterday, keel is .44 bar and tubes .25 bar. Written on it.
Interestingly, having bought a new valve off ebay as all my quicksilver ones didn't last 5 minutes, thus not having one for 3 years, I've now realised ive been running them at just over .1 bar, well under recommended. Will be interesting to see if I notice any performance difference. Will be out on the wknd.

Thanks young man, that's much appreciated..

Now on to aligning the front board with the valve as it seem somebody else has the same issue as me and has it off centre.

Cheers again.
